CHARLES AYRES', VAN BUREN, ARKANSAS. sTovEf Specification of Letters Patent.

Patented Jan. 1, 1907.'

, Application filed May .16. 1905. Serial No. 260,700.

such-as willenable others skilled in the art to whic it appertains to make and use the same. My invention relates to improvements in heating-stoves and its object is to provide a stove of this character having a novel arrangement of. air inlets and outlets whereby air can be directed either downward or upward through the grate or can be caused to circulate above said grate withoutpassing therethrough; 4 y

Another object is to provide a stove which will consume all noxious gases and prevent their escape into the surrounding atmosphere.

A still further object is to provide a heatingstove which will consume all kinds of coal, as well-as slack, and which serves, as a floorwarmer.

With the above and other objects in view the invention consists of a casing having a grate'therein disposed at a distance above the bottom thereof, and extending into the stove from the top is an air-inlet tube. Outs lets are located within the casing at points above and below the grate, and both outlets are connected to a common smoke-pipe and have dampers whereby either or both may be opened or closed at will. I

' The invention also consists in further novel construction and combination of parts hereinafter more fully described and claimed. In the accompanying drawings I have shown the preferred form of my invention.

In'said drawings, Figure 1 is a vertical sec.- tion through my improved heating-stove; and Fig. 2 is a section on line m, Fig. 1.

Referring to the figures by numerals of reference; 1 is a casing of any. suitable contoura' id having a substantially frusto-conioal top 2, providedwith a fuel-inlet opening 3, having a closure 4. The'ilat portion 5 of the top is normally covered by a ca 6, which may be suitably ornamented and w 'ch is pivoted-t0 the top 2, as at 7, so as to be readily swung to either side to permit of easy access'tothe portion 5. An air-inlet opening 8 is centrally located in the'fiat portion 5 of the stove-top and is normally closed by means of a damper 'ner, as by rivets 16*.

I portv for the grate.

9, which may be either of the rotary or sliding type. An air-inlet tube 10 extends downward from the opening 8 to a point within the upper portion of the fire-pot 11. A suitable grate 12 is disposed at the bottom of the lire-pot and has a movable portion 13, to

which access may be had through a door 14 within the casing 1. d

An ash-pan 15 of any preferred form is adapted to be located upon the bottom of the stove-casing and below the grate, and the lower compartment 16 of the stove, in which this pan is located, is of considerable Size, so I that air is free to circulate therethrou 11 either downward or u ward, according to t 1e arrangement of the dampers hereinafter referred to. The fire-pot ll'is substantially cup-shaped and narrower, at its lower end A than at its upper end, the upper end being of such a diameter as to snugly fit within the casing 1 and is secured thereto in any preferred manner, as by rivets 11, and the compartment 16 is formed by disposing an in-. verted-cu shaped cone 16 below the firepot 11 tie upper end of the cone-shaped member 16 being smaller than 'the lower end thereof and coincides with. the diameter of the lower end of-the fire-pot 11 and is adapted to abutthereagainst, while the extreme lowerend of-the cone-shaped member 16'is secured to the casing 1 in any preferred man- The' upper or reduced end of the member 16 is provided with inwardl' directed lips 16, upon which is seats the grate 12, said lips forming a sup- By having the. lower and upper ends, respectively, of the fire-pot 11 and cone-shaped member 16 tapered, a chamber 16 is formed around the. fire-pot and coneshaped member, the object of which is to protect the casing 1 from coming in direct contact with the end of the lire-pot containing the combustible material, and as the combustion takes place in the lower end of the.

ment 16, thereby forming 'a dead-s ace.

around the fire-pot and the upper end 0 the lower compartment 16.

If the heatshould become so intense to overheat the casing 1, surrounding the firepot, the door 14 may be removed, thereby l admitting cold air into the chamber 16, and thus reducing the temperature in the chamber.v Outlet-openings 17 and 18 are formed within the stove-easing at points near the l top and bottom thereof, respectively, and these openings communicate with'the smokeipe 19-of the stove. Dampers 20 and 21 are lbcated in the openings 17 and 18, respectively, and have arms 22 extending therefrom, whereb they may be readily manipulated manual y. Adoor 23 is located in the casing 1, near the bottom thereof, to permit the removal of the pan 15. This door has a damper 24 for regulating the admission of air therethrough. By closing the dampers 9 and 21 and opening dampers 20 and 24 air will circulate from thedoor 23 upward through-the rate 12 and out through openings 17, as in tie ordinary construction of stoves of this character. More or less of the es generated will, however, escape into the surrounding atmosphere, and to overcome this obj ectionable' result I preferably produce a downdraft by closing the dampers. 20 and 24: and opening dampers 9 and 21. Air will then enter through the opening 8 and tube 10 and pass downwardthrough the fuel and the grate and then into the lower compartment 16 and out through the opening 18. Any gases generated within the upper portion of the stove will therefore be carried downward into the fuel and consumed and there is no danger of their escape from the stove. If preferred, the two lower dampers 21 and 24 may be closed, and air entering the tube 10 will then pass outward through the opening "17 and will contact only with the up er portion of the fuel in the stove. The fue will therefore be caused to burn very slowly, and a great saving will therefore result. \Vhen the'downdraft is employed, the hot products of ,combustion will naturally heat the walls of the chamber 16 to avery high temperature, and therefore the stove is particularly adapted for use as a floor-warmer.

In the foregoing descriptionI have shown the preferr'edform of my invention; but I do not limit myself thereto, as I am aware that modifications mayl be made therein without l departing fromt advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention. I

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. In a stove, the combination with acas-' e spirit or sacrificing the ing, of a cu -shaped fire-pot within said-casing, the wal s of which are tapered, means to secure said fire-potto the casing, a coneshaped member below said fire-pot, the

lower end thereof being secured to the casing,

a plurality of lips at the upper end of said member, a grate seated upon said lips, said fire-pot and cone-shaped member'forming a chamber within the casing, means for. controlling the admission ofair to the chamber,- an airinlet tube extending into the casing above the grate, outlets within thecasing above and below the grate, asmoke-pipezextending from the outlets and means within the outlets for directing air hom the tube either directly to the smoke-pipe or through the grate to said pipe. I

2. In a.stove,-the combination Wiiill'fi. casing, of a tapered fire-pot, means to secure theupper end of the fire-pot to the casing, a cone:- shaped member below the fire-Potarid adapted to abut thereagainst, means to'secure the lower end of said cone-shaped member to the.

casing, whereby a chamber will be formed around the fire-pot and cone-shaped member and separated from the remainder of the stove, inwardly-directed lips at the upper end of said cone-shaped member, a grate dis posed on said lips and means to control the admission of air into the chamber surroundin the fire-pot and cone-sha ed member.

In testimony whereof I- lave signed my name to this specificationin the presence of two subscribing witnesses.
